DEVICE FOR DRAWING STEAM-BEER.

SPECIFICATION forming'part of Letters Patent No. 515,470, dated February27, 1894.

Application filed July 13,1893.

To all whom it may concern.-

Be it known that I, CONSTANT HARTH, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented an Improvement in Devices for Drawing Steam-Beer; and Ihereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to a device for drawing beer under a heavy head orpressure of gas. This class of fresh beer is known as steam beer indistinction from lager and other kinds which take longer in making andhave not so great a pressure of gas in 'them. This beer is usually madeand placed in casks which are delivered at places where beer is to besoldby the glass, and the beer is drawn directly from the cask. Thepressure of the gas is so great, however, that it is almost impossibleto draw the beer without allowing some of the gas to escape, whichproduces a great deal of foam, and after the cask is more than halfempty, there is not enough pressure left to keep the beer in a livelycondition.

My invention consists in the interposition of a chamber or receiverbetween the cask and the drawing off faucet, and in certain details ofconstruction which will be more fully explained by reference to theaccompanying drawings, in which- Figurel is a horizontal cross sectionof the receiver on line y-y of Fig. 2. Fig. 2 is a view of the faucetcomplete.

A is the cask, and Bis the outer case of the receiving chamber which hasone end adapted to be fitted into the cask in any suitable or desiredmanner. 0 is a chamber and passage within this case communicatingdirectly with the cask and curving to one side into the second chamberwhere it makes a turn at approximately right angles with its firstdirection and terminates in apassage as shown at C which leads into thesecond portion D of the receiving chamber. The device is fixed in thecask so that the chambers O O and D are in a horizontal plane, and notone above the other.

Within the chamber D is a valve E which is adjustable with relation tothe seat through which the passage 0' opens into the chamber D. Thisadjustment is produced by means of the screw-threaded shank F of thevalve Serial No. 480,413. (No model.)

fitting corresponding screw threads in the socket-piece G. This piece isscrewed into an opening in that part of the chamberD directly oppositeto the opening 0 and valve 0, and in line therewith. This socket piece Ghasa chamber G made within it, into which the end of the shank Fprojects. This chamber is normally closed by a screw-cap H and when thiscap is removed access is obtained to the chamber G, and by means of ascrew driver or other tool, adapted to fit the exposed end of the shankF, the valve E is accurately adjusted with relation to its seat. Thisadj ustment is so made as to leave a small space around the periphery ofthe valve between it and its seat, and through this the beer escapesslowly into the chamber D, the greater portion of the gas being retainedin the chamber G C so that the beer passes in acomparatively solidcondition from the chamber D into the faucet I which screws into theouter end of the receiver B as shown. When the faucet is closed and thepressure is equalized within all parts of the chambers O and D, any gaswhich remains therein will naturally flow back into the cask, beingdisplaced by the liquid which then fills the faucet and the chamber. Inthis manner I am enabled to draw the beer directly from the cask in acomparatively solid condition, with but little or no escape of gas, andthe gas which does pass into the chamber, will immediately pass backinto the cask by displacement as soon as th draw off cook or faucet isclosed.

I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a cask within which beer or liquid impregnatedwith gas is contained, of an intermediate receiver formed with internalhorizontally disposed chambers O and B and a connecting passage, a valvewithin the receiver adjustable with relation to said passage, and adischarge passage and draw off cock substantially as herein described.

2. A device for drawing steam beer consisting of the receiving chamberadapted to fit the cask and comprising the horizontally disposedseparate chambers formed within the receiver with an intermediatepassage and valve seat, a valve within the receiver adapted Having thusdescribed my invention, what Y piece through which the stem passes, andthe head formed upon the outer end of the stem to receive the tool forthe adjustment of the valve, together with the closing cap H,substantially as herein described.

In witness whereof I have hereunto set my hand.

CONSTANT HARTH.
